摘要
装载机铲斗销孔的加工精度直接影响铲斗的平衡,导致销孔及销轴磨损严重。文章分析了铲斗销孔加工技术要求,针对目前铲斗销孔加工工艺存在的问题,提出了采用双头数控镗床加工铲斗销孔的工艺方案,确定了机床的总体结构,工作原理和技术参数。阐述了机床防干涉镗削动力头外形和主传动系统的设计。该机床经企业使用效果良好,有效地保证了两组平行孔系的平行度和同组孔系的同轴度,提高了铲斗加工效率。
The precision of loader shovel pin hole directly impacts the balance of shovel and leads to serious wear of pin hole and pin roll.This paper analyzes the technical requirements of the shovel pin hole processing,puts forward the technology program used to process shovel pin hole with double-CNC boring machine against the problems of shovel pin hole machining process and determines the overall structure,working principle and technical parameter of the machine.The author describes the design of the boring machine antiinterference power head shape and the main drive system.The actual running results in an enterprise shows that the machine can enhance the processing efficiency and effectively ensure parallelism of two sets parallel holes and concentricity of the same group holes.
